xdm and autologin

Hello
(this is Google tranlation)
I use the Xfce desktop and I would like to use autologin.
The problem is that when I use autologin, I can not stop the computer with the icon.
I can not choose between stop, restart and logout.
I only have logout.
Do you know how to configure to have the same choice as when autologin is not acrive?
